DARCY A. YOUNG, OF MILFORD, MASSFOKUSFTTS, ASSIGNQR TO AMERICAN WRINGER COMPANY, OF WOONSOGKET, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

VTRINGEB.

Application filed April 28, 1919. Serial No. 298,282.

To all whom it may concern:

Be it known that I, DARCY A. YOUNG, a citizen of the United States, residing at Milford, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in VVringers, of which the following is a specification.

This invention relates to certain new and useful improvements in a wringer especially of the power operated type although it is well adaptable to the manually actuated wringer, and it has for its primary object and aim to cheapen and expedite the manufacture and assemblage of the wringer parts by casting the frame and guide board integrally into two separable body sections.

A further and important object of the invention is to provide a quick releasable pres sure device for exerting pressure on the squeeze rolls, such device being rendered inoperative merely by a slight push of the hand against a safety locking lever which is readily accessible.

The invention is further found in the features of construction and the arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawings wherein Figure 1 is a front elevation of the improved wringer.

Fig. 2 is a top plan view thereof.

Fig. 3 is an end elevation, and Fig. 4 is a vertical section transversely of the wringer, being taken on line 4E4E of Fig. 1.

Fig. 5 is a vertical longitudinal section through the wringer on line 5.5 of Fig. 2.

Fig. 6 is a top plan view of the wringer with the pressure device inoperatively disposed.

Fig. 7 is a vertical longitudinal section therethrough on line 7-7 of Fig. 6, and

Fig. 8 is a detailed horizontal'section on line 8-8 of Fig. 5-depicting the manner of connecting the frame body sections together at their lower ends.

The complete wringer frame is constructed of two separable sections 1 each of which is cast preferably from a compound of aluminum and are identical in formation, consisting of end frame members or uprights 2 connected adjacent their upper ends by the brace bars 3 and adjacent their lower ends by the guiding boards 4 which extend outwarcllv therefrom. The frame uprights 2 are of U-section, as depicted in Fig. 8, their Specification of Letters Patent.

hollow sides opposing each other when the sections or halves of the wringer frame are operatively joined. Disposed in the lower ends of the hollow uprights and connecting them in opposing pairs are horizontal links 5 secured at each end to a respective upright 1 by a screw fastener 6. The upper ends of the two halves or sections are joined by a fitting 7 having an inwardly overhanging lip 8.

The frame uprights have their inner upper edge portions cut away to define a vertioal gu'ideway 9 in which the trunnions 10 of the rolls 1.1 find bearing, the bearing 12 for the upper wringer roll being slidably engaged with the composite upright frame member and is normally held down onto the roll trunnion by the superposed coiled spring 13. The upper end of the coiled spring supports a vertically slidable bearing 1 1 on which pressure is applied to vary the pressure between the wringer rolls.

Pressure is applied in the present instance by a quick releasable device comprising a breakable bar 13 having its sections connected by means of an upwardly breaking hinge 16 and its outer ends slightly reinforced and engaged beneath the opposing inturned lips 8. Said outer ends of the pressure releasing bar 15 having vertical threaded openings in which are engaged adjusting screws 17 having hand wheels 18 by which they may be turned to cause the lower end of said screws to engage and force the cap bearings 14 downwardly. Pivotally carried on the inner end portion of one section is a locking lever 19 having a hook-shaped latch 20 for swinging to and from engagement with the keeper lug 21 fixed on the inner end of the companion bar section. The extent of swing afforded the locking lever is defined by a limit stop 22 disposed in the path of the same and when the lever engages the stop its latch end is operative with the keeper lug and when one of the lever handles 23 is engaged with said stop the latch end is disengaged from the keeper thereby permitting the bar to break at its hinged joint.

Two handles are provided on the lever extending in opposite directions therefrom and at its opposite ends, said lever lying transversely of the bar. This arrangement disposes the handles on opposite sides of the pressure releasing bar and gives to the entire lever a Z-design, its pivot being located at one corner and its latch at the other. The handles are broadened and depend on oppositesides of the bar to afford ample surface for'the operator to easily strike with his hand when emergency calls for the release of the pressure on the rolls. This may occur when a bunch of clothing comes between the rolls or when the operators hand is accidentally drawn in therebetween for in such event the operator would push against the handle lever with his free hand. A handle on each side of the wringer permits the safety device to be operated from either side.

In operation, the release bar is normally disposed as illustrated in Figs. 1 and 5 when .therolls are intergeared as at 24. Should it become necessary to quickly release the pressure between the rolls the locking lever is rendered inoperative by striking either handle. The upward pressure of the springs on the adjusting screws will then cause the bar 15 to break at its hinged joint, as in Fig. 7, and this will withdraw the ends of said bar from beneath the overhanging lips 8 so that the cap bearings 14 will be unhindered toward rising out of their guides. The rolls will then readily separate and their gears bedisengaged to relieve the object held therebetween.

Having thus described'my invention, what I claim as new and desire to secure by Letters Patent;is

1. In awringer, a frame including end uprights each composed of two sections, the confronting partsof the sections at the lower ends of the latter being in abutting engagement and hollowed outto receive the links, the hollowed out parts extending through the bottom ends of the sections, links in said hollowed out parts to close the bottom ends of the hollowed out parts, means extending through the outer sides of the sections and the links to secure the links to the respective sections, the inner faces of the sections above said hollowed out parts being cutaway, rolls having journals mounted in said cutaway parts, springs in the cutaway parts for tensioning the rolls, and means to secure the upper ends of the sections against movement.

2. I11 a wringer, a frame including end uprights each composed of two sections, the confronting parts of the sections at the lower ends of the latter being in abutting engagement and hollowed out to receive the links, the hollowed out parts extending through the bottom ends of the sections, links in said hollowed out parts to close the bottom ends of the hollowed out parts, means extending through the outer sides of the sections and the links to secure the links to the respective sections, and fittings arranged over the upper ends of the sections and secured to each to hold same together, said links having their ends received in the hollowed-out parts so as to be concealed thereby, the bottom faces of the links only being exposed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
